an oil well into which the oil from the various bearings of the motordrains and from which it is drawn and 11e-circulated. A pump forv thispurposeis shown at 13 in Fig. 1, the oil being drawn from the bottom ofthe crank case where it settles through the screen 14, and pumpedthrough a conduit 15 in which there is a pressure regulating valve 16,toa screen 17 and the I 18 surrounding the same. From the chamber 18 theoil is led under pressure through pipes 19-and 2O to the variousbearings of the motor. 'Said bearings will be hereinafter furtherdescribed1v Cylinder blocks 21v are shown as formed separately from thecrank case and detachabl secured thereto.

An engine of four c luider. blocks 21 is shown in the illustrative forniof the invention herein, each block comprising three cylinders, twoblocks being arranged withtheir cylinders in line and the two pairs ofblocks being in V rela tion. Thus a 12 cylinder V type motor isillustrated.

The cylinder blocks 21 are water jacketed as at 22 and suitable inlets23 and outlets 24 are provided. Each of the cylinders han` an inletport25 trolled b" puppetvalves 27 and 28.1es ectivey. i )rings 29 maintainthese va ves yiel ingly spark plug 30 Vfor each of the cylinders. Y

' A.- carbureter 31 is preferably 'mounted' .in the space between the'cylinders and branched intake headers 32, one for the cylinders on 'oneside'oi the motorand another for the cylinders on the other side of theand an outlet port 26 con-` in closed position, There is a A motor,connect the carburetor with the various intake ports of the cylinders.Suitable exhaust'pipes 33 are connected with the -exhaust ports ofthemotor. n

Mounted in the main bearings of the crank case is a crank shaft 36. Inthe form shown this crank shaft has similar disks or cheeks 37, all ofwhich. are connected together by the crank pin and main bearing partsof' th'e crank shaft.

The entire gear casing 58 is substantially ot Y form, the lower .part ofit extending down around the gear 55, and the upper art being in theJform of two branches exten ing diagonally upward adjacent to butseparated from the rear ends of the cylinder blocks.

' The upper part of each of these branches ofthe gear casing is formedbyea detachable esame? cap 84, which as shown particularly in F 2 isprovided with an oil filler spout 65. Thus the oilin the crank case maybe brought to the proper level by introducing oil through the spout 65,Where it will enter the gear cas ing 58 and run down into the crankcase.

l'n the motor herein shown, the camshaft and operating` mechanism forthe valves 27 and 28 are in the forni of a detachable unit lor each ofthe two pairs of cylinder blocks. Each such unit comprises a tubular camshaft casing 88 Which extends lengthwise ol the motor and which ismounted on top of and connects the tivo alined cylinder blocks. Thiscasing is divided into several compartments 67, 88 and 69, by bearings70, 7l and 72 for front end of the cam shaft 73. A supplementary bearing72 may be provided as shown in each of' the cornpartinents 67 and 68.The cams 74 formed on the cam shaft 73 are all arranged in .the tvr maincompartments 67 and .68 and the cam shaft extends through the frontbe'ariu?2 and into the end cornpartment 89. his end compartment 69 isvery small 'compared with the other cornpartments and is termed largelyby a cao 69 screwed on to the end of is supplied With oil under pipe 20which is a continuation of the pipe 20 shown in Fig. l. Any otherequivalent means may be used to supply oil under pressure to thiscompartment.

The cam shaft 73 is drilled out to malte it hollow and'oil leads 75 are.provided from its interior to eaclrof the bearings 70, 7l and 72. Therear end of the cani shaft is closed but the :front end is open to thecompertinent 69 so that the oil under pressure in that compartmentpasses into the cani shaft and through the oil leads T5 to the bearingsabove referred to. The oil flowing from these bearings accumulates inthe compartments G7 and 68, which are. interconnected by a channel 78,similar channels 76 being provided in the bearings 72 and from the rearcompartment 87 it overflows through the openings 7'? Fig. through thebearing 70 into the gear casing 58 and down into the crank case where itis collected and again circulated as herein above described.

The con'ipartinents 67 and G8 above referred to are formed W 'h topopenings 78 above the various cams on the cani shaft 73. Each of theseopenings has a cover @"9 and between the cover and the casingr ispivotally supported one or more rock shafts 80. Each of these rockshafts 8O is drilled.

out as shown for instance in Figs. l and and has an oil lead 8l leadingfrom its interior to its hearing' surface. An oil cup 82 is also formedin the upper part of the rock .shalt and a downwardly extending lug` 88on the Cover T9 directly over the cup 82 causes soule or the oilsplashed up onto the cover to dep into the cup. This oil then thecasing. t. pressure by trains ofgears Which passes into 'the roel; shaft8C and to its been v in# surface.

ach roclr shaft has an arm 84 upon which is a roller 85 in contact withone of the earns 74's of the caro s raft, and the end ot the rock shaft8O that extends outside of the cam shaft casing is provided with an arm86 haring an adjustable plunger 87 in contact with the stem of one otthe valves 27 and 28.

From the above description it will be seen that the camshaft casing 66,the camshaft, and all of the rock shafts and other operatarts may beassembled before the unit is aced on the motor. lt may then be attachedto the tops of the cylinder blocks by the lugs 88 and bolts 89. It mayalso be secured to the gear casingr 58 by the cap 64 Whichhas a part 9()cooperating with a part 91 on the gear casing, which parts are arrangedto clamp the tubular `casing; G6 between them. Endwise movement or' thetubular casing 66 relative to the gear casing 58 is prevented by reasonof the llanges 92 on the tubular casing. By this connection of` casingsand cylinder blocks a very strong and ri id construction is obtained. l

gThe spur gear on the crank shaft has been herein above referred to.This gear forms one oic a train 01"' gears between the crankshaft and anauxiliary shallJ 93 which, )in the forni ofy the invention shown, ismounted directly above and parallel to the cra-nir shaft. This auxiliaryshaft 93 is mounted in bearings 94 and :95 in the gear casing 58 and isshown connected Witha generator 97 for supplying electric current to thespark plu s of the motor. The generator .is mounts on a bracket 98arranged between the cylinder; blocks.

Freni the auxiliaryshaft 93 there are two extend in opposite directionand are arranged to operate the two earn shaft at ouehalt crank shaftspeed, Of these trains of gears, only several gears of one of the trainsareherein shown., including a gear 107 nieshin with an idler gear 109,which meshes with cured to the rear end of one of the cam shafts T3. Asimilar idler gearlOQ meshes with the gear 108 and .itsell meshes with agear ll() on the other cam` shaft 78. lt will be understood that thegear 106 has just half as many teeth/as each of the gears lll), so thatthe cam shaft 73 will operate at one! half crank shaft speer, foroperatingthe motor on the four stroke cycle. I

All of the gears above referred to are shown as of the straight toothspur type but it Will be understood that other equivalent gears may beused for the saine purpose..

Referring to the arrangement oll the cam shaft casing' and the gearcasing', it will be seen that the former niay be reniorcd by removingthe bolts 89 and the caps4 (it. `rAlso the upper part 6l of the gearca/*sing may bc a gear ll() seof me @aging will deacned and @his par@110% am. il@ ma wel Hm uppe parts 01E ha waiving@ ohm gems 106, l0? ami108.
